26.  The maximum twisting moment a shaft can resist, is the product of the permissible shear stress and 


27.  For a simply supported beam with a central load, the bending moment is 


28.  For a given material Young's modulus is 200 GN/m^{2} and modulus of rigidity is 80 GN/m^{2}. The value of Poisson's ratio is 


29.  The ratio of the moment of inertia of a circular plate and that of a square plate for equal depth, is 

Answer: Option D Explanation: For circular plate, MI = π*d^4/64. For square plate, MI = d^4/12. So, Ratio = MI of circular plate/MI of square plate. = 3*π/16. 
30.  The force in member U_{2}L_{2} of the truss shown in below figure, is
